A cool southerly airflow lies over New Zealand on Monday, strong at first about the lower and eastern North Island. Overnight a ridge moves over the South Island.

For much of the western North Island expect high cloud to gradually decrease during the day and sunny areas become more frequent, a few showers cling to coastal parts of Taranaki during the day however and Northland may see a few isolated showers late afternoon / evening. Showers ease during the day along the east coast, sunny spells at times. Areas of cloud about Wellington with the odd shower, many dry spells too, strong Southerlies ease during the day.

Mostly sunny along the South Island’s West Coast, showers at times in the east with a few snow flurries to 500m (perhaps 400m at times). Showers ease during the day then clear at night. Morning showers about Southland and Otago clear then sunny areas break through from afternoon.

Becoming frosty overnight for much of the inner South Island and parts of the inner North Island.
